Application filed June 30, 1814, Serial No, 848,120. Renewed Sctober 16, 1516. Serial No. 126,

To all whom it may concern Be it known that I, JOHN B. BARNETT. a citizen of the United States, residing at Fort Worth, in the county of Tarrant and State of Texas, have invented certain new and useful Improvements in Display Ad vertising-Machines, of which the following is a specification.

My invention relates to advertising devices and more particularly to devices which. will exhibit cards or advertising sheets at regular intervals; and the object is to provide advertisingmachincs which will display advertisingcards or sheets at regular intervals and hold the same in exposed positions long enough for the advertising matter to be read and to provide improved mechanism which will operate intermittently and regularly the devices for displaying the advertising sheets and which will act with certainty and which will prevent movement of the advertising sheets while they are being read or inspected and to provide machines which have no delicate parts that will be thrown out of working conditions during operations.

Qther objects and advantages will be fully explained in the following description and the invention will be more particularly pointed out in the claims.

Reference is had to the accompanying drawings which form a part of this application. 7

Figure 1 is a front elevation of the ma.- chine with a. part of the casing broken away to expose the operating mechanism. Fig. 2 is a diagrammatic plan view of the gearing for operating the display cards or sheets. Fig. 3 is a detail view of a mutilated pinion for turning a sheet or card intermittently. Fig. 4 is a detail of one of the carrying disks, illustrating the movement of the dis play arms. Fig. 5 is a detail view of the journals of the rotating posts or shafts. Fig. 6 is a face view of the controlling disk and operating rack. Fig. 7 is an edge view of the same. Fig. 8 is a detail view of a contact making device used for producing lights at the proper moments.

Similar characters of reference are used to indicate the same parts throughout the several views.

The machine is provided with a casing 1 which may be suitably ornamented. The

lower part of the casing is cut away at 2 to show the mechanism for operating the ad vertisinp; sheets or cards 3. The sheets 3 are displayed by quadrangularframes which may be constructed of pipe. One vertical side portion a of the carrying frame extends above and below the cards or display sheets 3 and is journaled in disks 5 and 6 which are horizontally disposed and which disks are mounted on a verically disposed roatina' shaft 7 which is journaled in a socket S and a suitable journal in the upper part of the casino; 1. The pivot post 4 of each display frame is provided with a cone shaped collar 9 which is rigid with the post and ball bearings 10 are placed between the collar 9 and the carrying disk 5. The quad rangular display frames are thus provided with antifriction bearings. The disks 5 and 3 are rigid with the central shaft 7. The quadrangular frames 11 may be connected to the rotatable posts 1- by T-pipes 12. Each rotatable post t is provided with a mutilated pinion 13 rigid therewith. Provision is made for rotating the shaft 7. A shaft ll is provided with a worm gear wheel 15 which is driven by a worm gear wheel 16; The sl aft 1% is iournaled in bearings 17 which are rigid with the base casting 18. The casting 18 has a socket 8 rigid therewith. The shaft 1 1- also carries a contact making and braking wheel 20 for'intermit tentlv operating a lighting" system (not shown). A disk 21 is rigid with the shaft 14: and is provided with a cam rack 22 which projects out of the plane of the disk. The rack 22 drives the pinions 13 for turning the advertisingcards or sheets 3.

In operating the display sheets 3,.the cam rack 22 gives two motions to the display sheets,-it rotates each sheet on its pivot post 4 a part of a revolution and also moves all the sheets about the main post or shaft 7 by rotating the frame supporting disks 5 and 6 which carry the sheet holding frames 11. Considering Fig. 4-, the frames 11 on the right of the figure move on around in a desultory manner until the pinion 13 of each frame 11 comes into mesh with the cam rack 22 which rotates each frame 11 on its post 4. During the time while the rack 22 is rotating a post 4, it moves the same post from one position to another,m0ving it exactly the distance from one center of a shaft 4 to the center of the adjacent shaft so that when the rack 22 acts once it moves all the pinions 13 one step forward and the disks 5 and 6 are moved with the pinions 13. The disks 5 and 6 and the pinions 13 are prevented from moving in either direction by the disks 21 except when the rack 22 is acting on a pinion 13. The disk 21 is so timed that the shoulder 23 will pass below the path of the pinions so that the rack 22 will push the pinion past the disk 21 at the same time the rack is rotating the pivot post 4 and rack 22 will move the pinion 13 far enough to the right to allow the part of the disk behind the rack 22 to rise up between two pinions 13. The pinions 13 and the disks 5 and 6 will then be held stationary until the shoulder 23 again passes below the path of the pinions 13 and the rack 22 commences to turn the pinions. The rack 22 moves a pinion 13 from one side of the disk 21 to the other every time the disk 21 turns over once. The disk 21 thus holds an advertising card stationary while the disk is turning except while the rack 22 is passing and turning a pinion. The time the display sheet stands still thus depends upon the time that is required for the turning of the disk 21. The pinions 13 are turned approximately 180 degrees by the rack 22. Fig. 4. of the drawings indicates how much the frames 11 may be swung on the pivot posts 4..

What I claim, is,

1. An advertising machine having a casing, a base rigid therewith, a socket formed on said base, a vertically disposed shaft adapted to rotate in said socket, disks rigid with said shaft, a plurality of frames pivotally mounted in said disks, pinions for turning said frames, and a driven disk having a rack rigid therewith and extending at an angle from the face of the disk for turning said pinions and for changing the positions of said pinions.

2. An advertising machine having a eas- Gopies of this patent may be obtained for five cents each, by addressing the in said disks and projecting below the lower disk, ball bearing collars holding said pivot posts in operative positions, gearing on the lower ends of said pivot posts, a driven shaft, and a disk rigid with said driven shaft andzpositioned with a portion of the disk adapted to project upwardly between two pinions and having a rack projecting therefrom at an angle to the faces of the disk and adapted to drive each pinion in succession and simultaneously to move all of said pinions one step at one time.

3. An advertising machine having an open front casing, a rotatable shaft vertically disposed in said casing, a pair of disks rigid with said shaft, a series of quadrangular frames, each provided with a pivot post j ournaled in said disks and extending below the lower disk, .a pinion on each pivot post below the lower disk, a driven shaft positioned below said pinions, and a disk rigid with said driven shaft and having a segment out therefrom whereby a pinion may pass horizontally through the disk and said disk having a rack formed thereon at an angle to the faces thereof and adapted to rotate said frames by means of said pinions and simultaneously to move a pinion from one side of the disk to the other whereby all of said display frames are moved a step at a time periodically and held stationary for regular periods of time.

In testimony whereof, I set my hand in the presence of two witnesses, this 26th day of June, 1914.
